Prevalence, Pathology And Associated Risk Factors For Dictyocaulus Infection Among Slaughtered Sheep

Pseudogymnoascus destructans, the scientific name for White-Nosed Syndrome is a cold dwelling fungus that has been running rapid in the United States. The disease has made prevalence here after being brought over from Europe and Asia. Research has even been found that bats in Europe may

There are still people today who do hunt as their main source of food. A lot of these people choose to hunt for their own meat vs. buying it because they feel it is fresher. Also, because they know where the food comes from. These people who hunt for their own food also often also use the fur for

5. What species is the intended host for the Baylisascaris nematode and what symptoms does it cause in this host?

The lifecycle of a heartworms begins when a female mosquito ingest blood containing microfilariae from a heartworm infected animal. Inside the body of the mosquito, the microfilariae develops into first stage larvae (L1) and then undergoes two more process to develop into third stage larvae (L3) of which is the infective stage. Depending on the temperature, this development process can take between eight and thirty days. At this point, when the infected mosquito attaches to a cat and feeds on its blood, the third-stage larva is transferred into the mosquito bite wound. Within three days of entering the cat, the L3 molt to the L4 stage in the tissues and muscles that lay just below the skin of the cat. After about two months of migrating through the muscles and tissues, the L4 undergoes a final development into immature adult heartworms. Seventy to ninety days post infection, the immature adult heartworms then enter a peripheral vein and are carried by the cat’s blood circulation system to the caudal pulmonary arteries. This is where the majority of heartworms are cleared from the cat due to a mass immune response, but a few may continue development into adults. Once the heartworm develop into adults, they invade the heart first and then spread to other organs in the body and cause

The last forty-five years has seen a significant increase in world animal protein production. Since 1967 global production of poultry meat has increased by around 700%, eggs by 350%, pig meat by 290%, sheep and goat meat by 200%, beef and buffalo meat by 180% and milk by 180%. Livestock are increasingly important to the food security of millions of people. (Leyonhjelm 3)

The new population of cane toads has been quickly growing throughout Australia while carrying with it, a parasitic nematode, rhabdias pseudosphaerocepala. Once infected with this lungworm, both adult and metamorph toads can experience stunted growth and reduced stamina. This is a problem that is effecting native species. When predators feast on these toads, they become poisoned. Introduced pests can sometimes be controlled by using native predators or competitors. By conducting experiments and finding possible solutions, researchers may be able to protect these native species.

Fasciola hepatica, commonly known as the liver flukes, is parasites that are mainly located in hosts’ liver, feeding on blood of its host. The lifecycle of liver flukes start by host consuming plant which the surface were covered by liver flukes’ cysts. The metacercariae would be released from the cysts after they get into duodenum of the host. The metacercariae would then burrow through the intestines and liver, eventually got into the bile ducts (Kaewkes 2003). They spend approximately 8 weeks to become adults, which can produce up to 25,000 eggs per day. Eggs would be exterminated via faeces, which start the cycle again (Swales 1935). Fasciolosis is a serious global problem as a disease. In 1999, there were approximately up to 40 million sheeps and 6millions cattle fed on pastures which liver fluke is endemic. Fasciolosis does not only kill cattle but also reduce milk productivity and quality. Graziers need to spend about $10 million per year just to prevent fluke itself and production

The new guinea flatworm is from the united states of America.this worm is native to the island of New Guinea where it was originally to have been found in. You can find these worms in tropical areas,coastlands ,planted forests, riparian zones shrubs and urban areas as well.it feeds on earthworms ,slugs and arthopods. This worm can harm the snail called The Giant East African Snail. This worm also can mainly eat mollusks and it especially likes to prey on snail. To hunt for it's prey the worm deposits itself to the bottom of a cabbage leave. It also can follow snail mucus trails to find it`s trail. It also has a infectious rate at least 14.1% and this thing usually lives on cabbage leaves. This worm not only affects the whole population of animals or a specific area this worm can affect humans as

The goldenrod gall fly (or Eurosta solidaginis) is a parasite whose life depends upon and revolves around the goldenrod plant. After mating, the female gall fly uses its ovipositor (structure used to inject eggs into a plant) to insert its eggs into the stem of a goldenrod plant. After about ten days, the fly larvae hatch and begin to eat the inside of the plant. The saliva of the larva contains a chemical that causes the plant to swell, creating what is known as a gall; this serves as a food source and a protective shell for the growing larva. When fall approaches, the larva digs an escape tunnel by which it will later exit the gall as an adult; however, the larva does not complete the tunnel, instead it leaves a thin membrane of plant material for protection (Abrahamson & Heinrich, n.d.). E. solidaginis larvae then pupate in late winter or early spring, and leave the gall as adults soon afterwards (Abrahamson, Sattler, McCrea, & Weis, 1989). Once freed from the gall,

Animals such as sheep, cattle and pigs supplied more meat to bulk up native diets,

With a rich historical background of the sheep industry for the United States, political, sociological and economic events have driven the many courses of change since colonial times. Raising sheep and trading wool became a major enterprise and a central issue of the Revolutionary War. Imports of sheep from Spain during the 19th century provided a foundation of creating a national wool industry and helped the development of sheep industry in the west. The biological ability of sheep to efficiently produce fiber at fine quality and meat continues to be used as a valuable resource. The continuous reduction of sheep population has made a change in the production industry. It caused the wool and meat production to decline greatly. This presently

The wooly adelgid is a tiny, deadly insect that feeds on Eastern Hemlock, slowly killing it. This insect came from Japan in the 1950’s, and has spread ever since, aided by wind, birds, and even hurricanes.

Pinewood nematode is transmitted from tree to tree by pine sawyer beetles which overwinter as larvae in dead pines or pine logs which still have the bark attached. After pupating, the adult pine sawyer beetles, carrying nematodes in their tracheae, fly to healthy host pine trees where the nematodes enter through feeding wounds. Pinewood nematodes migrate to resin canals where they feed and rapidly reproduce. The resin canal system is damaged and water movement in the tree is disrupted. Once the pine tree dies the nematodes continue to feed and reproduce on blue stain fungus which infects the tree. In summer, female pine sawyer beetles carry nematodes as they fly back to dead pine wood where they lay their eggs. Eggs

Without the presence of bovine dung beetles in Australia, the dung from imported cattle has cluttered pastures and fashioned vermin. Research has questioned if the imbalance between bovine dung beetles and dung were to be stabilized, then the pastures would be used to their best ability and the growth of insect pests would decrease. Due to intensive research on the effects of the imported Afro-Asian Onthophagus gazella in Hawaii, the O. gazella dung beetle was introduced to Australia after undergoing thorough sterile conditions to destroy potentially harmful mites and other transferrable germs. The results of the importation were the elimination of a bovine dung pad in about 24 hours, the fertilization and richness of the soil, and the elimination
